Current DAVx⁵ versions require Android 5.0 or later. Older Android versions are not supported anymore, but you can use old DAVx⁵ versions which were compatible with Android <5. However, all DAVx⁵ versions require Android 4 or later.
Older DAVx⁵ versions work with Android <5, but there is no support and there won't be any updates, including security updates. We strongly recommend to update your Android device to Android 5.0 or later (maybe using a custom ROM) and use the latest version of DAVx⁵.
|DAVx⁵ version||required Android version|
|≥ 3.0||≥ 5.0 (Lollipop)|
|≥ 1.9.3||≥ 4.4 (KitKat)|
|≥ 1.6.3||≥ 4.1 (Jelly Bean)|
|≥ 126.96.36.199||≥ 4.0.3 (Ice Cream Sandwich)|
|<188.8.131.52||≥ 4.0 (Ice Cream Sandwich)|
App stores (like Google Play): We try to keep multiple versions online at the same time, so that you can install DAVx⁵ even if you have an old Android version. However, we may not be able to keep old versions for ever.
F-Droid / direct APK: If you really need to install an old version of DAVx⁵, we recommend to install F-Droid and activate "F-Droid Archive" in the repositories (F-Droid / Settings / Repositories, see screenshot).
Then you can use an old version which is compatible with your device.
You may notice crashes and other misbehavior with latest formally compatible DAVx⁵ version because compatibility was not tested enough anymore. In this case, use an even older version, which should be compatible again.
